The gear 20,

Said shaft 6 has in its inner tends through and rotates in the sleeve 3 and 5 end a nut-socket 9 of square or polygonal has on its opposite end an operating crankhandle 24, by means of which the socket-shaft 6 may be rotated by reason of the meshing gear 20 and 22.

In order to hold the tire-bolts while their nuts are being applied or removed, I provide in the arm or portion 5 of the frame 2 a sliding bolt-clamp 25. This clamp comprises a rod 26, which is slidahly mounted in an inwardly-projecting socket 27, formed in the portion or arm 5. Said rod 26 consists of an outer cylindrical portion 28 and an inner reduced square or polygonal-shaped portion 29, which terminates in a beveled end or point 30, adapted to engage the end or the notch in the end of a bolt or screw. The squared portion 29 of the rod slides through a similarshaped opening at the inner end of the socket 27, and surrounding said portion is a coilspring 31, which is confined between the enlarged portion 28 of said rod and one end of said socket, so as to exert its energy to move or slide the rod 26 outwardly. The said rod is moved inwardly against the tension of said spring and held in engagement with a bolt or screw by means of a spiral-shaped cam 32, which is provided upon the inner face of a disk 33, mounted to rotate upon the sleeve 3. This disk is confined between the end 28 of the rod 26 and an integral arm or bracket 34, which is provided upon the outer end of the portion 5 of the frame, so that when said disk is oscillated by means of the handle 36, provided upon it, the spiral cam 32 will engage and operate the clamping-rod 26, as will be readily understood.

The construction,operation,and advantages of the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings.

It will be seen that the machine may be readily applied to or removed from a vehiclewheel and that it may be quickly adjusted for wheels of any size. When it is mounted upon a wheel, as shown in Fig. 1 of the drawings, and the operating-crank is turned in one direction or the other, the nut will be applied to or removed from the bolt according to the direction of rotation of the wrench-socket.

While I have shown and described the preferred embodiment'of my invention, it will be understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent. is-

A bolt-holding machine-wrench comprising a sleeve, a pair of arms disposed opposite each other and secured to the sleeve, a longitudinally-movable wrench-shaft having its bearings in one of said arms, a gear splined on the wrench-shaft, and bearing against the outer side of said arm. the latter having a device to prevent outward movement of the said gear on the said shaft, a longitudinally-movable, non-revoluble clamping-rod mounted in the other arm, a bracket extending outwardly from said arm and terminating at a point opposite and spaced from the clamping-rod, a

spring to press the clamping-rod outwardly, a shaft revoluble in said sleeve, a gear on said shaft engaging the first-mentioned gear, and a revoluble cam mounted on said shaft, hearing against the stop formed by the bracket and having on its inner side a concentric wedge-face engaging the outer end of the clamping-rod, substantially as described.

In testimony whereof I havehereunto set my hand in presence of two subscribing witnesses.
